LM1877 Datasheet | National Semiconductor

Description The LM1877 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8Ω loads. The LM1877 is designed to operate with a low number of external ponents, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers, etc. Each power amplifier is biased from a mon internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally pensated for all gains greater than 10. n n n n n Wide supply range, 6V- 24V Very low cross-over distortion Low audio band noise AC short circuit protected Internal thermal shutdown Applications n n n n n n n Multi-channel audio systems Stereo phonographs Tape recorders and players AM-FM radio receivers Servo amplifiers Inter systems Automotive products Features n 2W/channel n - 65 d B ripple rejection, output referred n - 65 d B channel separation, output referred Connection Diagram Dual-In-Line Package or Surface Mount Package DS007913-1 Top View Order Number LM1877M-9 or LM1877N-9 See NS Package Number M14B or N14A © 1999 National Semiconductor Corporation DS007913 .national.
